Michael Weghorn e702e27795 Handle CPDB lib in configure/build system
In preparation of Biswadeep's upcoming GSoC changes (see [1])
to update the CPDB (Common Print Dialog Backends) support to the
latest version and use the CPDB C API, add a
corresponding `--enable-cpdb` autogen option
(disabled by default).

When CPDB is enabled, check for the cpdb-frontend
library, define `ENABLE_CPDB` and set the compiler
and linker flags for building the `CPDManager`
(in vcl/unx/generic/printer/cpdmgr.cxx).

Add checks for existing code using `CPDBManager`,
so it only gets used when when CPDB is actually enabled.

While the cpdb-frontend library is currently not
actually used in `CPDManager` yet (as the previous approach
tried to use some DBUs API directly), it will be in
Biswadeep's upcoming changes.

With this commit in place, an `--enable-cpdb` build
works with this additional local test change in place
to actually make use of the library:

C/C++ Configuration Created by configure Script

These are configuration files for various features as detected by configure.

Include only those files you need (in order to reduce rebuilds when a setting changes).

Settings here are only C/C++ #define directives, so they apply only to C/C++ source, not to Makefiles.

Adding a New Setting:

  • do AC_DEFINE(HAVE_FOO) in configure.ac when a setting should be set
  • choose the proper config_host/config_XXX.h file to use
    • if it is a global setting (such as availability of a compiler feature), use config_host/config_global.h
    • otherwise check if there is a matching config_host/config_XXX.h file
    • if none matches, add a new one:
      • add config_host/config_XXX.h.in here, with just #ifndef include guard
      • add AC_CONFIG_HEADERS([config_host/config_XXX.h]) next to the others in configure.ac
  • add #define HAVE_FOO 0 to the config_host/config_XXX.h, possibly with a comment (do not use #undef HAVE_FOO, unless the setting has more values than on/off)
  • add #include <config_XXX.h> before any #if HAVE_FOO in a source file
  • make sure you use #if HAVE_FOO for on/off settings, do not use #ifdef
